Pneumatic Connection
Clean all pipelines to remove dirt and scale before installation.
Apply a minimum amount of pipe compound to the male threads
of the tting only. Do Not use teon tape as a sealant. Start
with the third thread back and work away from the end of the tting
to avoid contaminating the transducer. Install the transducer in
the air line. The inlet and outlet ports are labeled on the ends of
the transducer. Tighten connections securely. Avoid undersized
ttings that will limit the ow through the transducer and cause
pressure drop down stream.
Electric Connection
Make connections as shown in Figure 9.
NOTE:
Oil free air is required. Use a lter to remove dirt
and liquid in the air line ahead of the transducer.
If an air line lubricator is used, it MUST be located
downstream to avoid interference with transducer
performance.
The user is responsible for insuring that the
environment in which the unit will be installed and
the operating gas are compatible with the materials
in the transducer.
CAUTION: Effective November 1997 (DATE CODE NE), the
DIN Connector terminal connections have been changed. The
ground connection has been moved from terminal #3 to the ( )
terminal. When replacing an existing unit, correct wiring on the
mating connector.

Shut off the valve that is supplying air to transducer.
It is not necessary to remove the Transducer
from the air line.
Remove the Orice Assembly from the unit. For
detailed information see Figure 1 “T6000 Calibration
Conguration on page 1.
Clean with alcohol and dry with compressed air.
To clean the Orice, use the following procedure:
MAINTENANCE
Parts must be completely dry before reassembling.
If the standard maintenance procedure does not
correct the trouble, install the appropriate Service
Kit below:
16798-1 (3-15, 3-27 & 6-30 psig
Standard Range)
18238-1 (0-30 psig Extended Range)
18239-1 (0-60 psig Extended Range)
18240-1 (0-120 psig Extended Range)
18039-1 (Explosion-Proof Base)
Service Kits also include Gasket, O-Rings, and
Membranes to replace "W" Option product.
NOTES:
TROUBLE-SHOOTING
